Passby finds real points of interest near you and uses Apple Intelligence to bring each one to life — word by word, as you travel.
Built for walkers, passengers, and frequent flyers. Passby adapts to how fast you move.
Powered by MapKit's points of interest database — parks, museums, restaurants, landmarks, and more. No made-up results.
Every pin gets an AI-generated headline and description, streamed word by word using on-device Foundation Models. No API key, no cloud cost, no latency.
Your path is drawn directly on the map as you move. See exactly where you've been in this session.
Walking, Passenger, and Plane mode each tune the refresh distance and surface relevant data — speed, heading, and altitude when you need it.
Every place you tap is logged with the time and travel mode. Your journey history syncs to your account via Firestore so it's there when you come back.
Sign in with Apple and leave thoughts on any place. See what other travelers are saying about spots near you in real time.
Say "Find places nearby in Passby" to open the app and start discovering. No tapping required.
Moving too fast to be walking? Passby notices and offers to switch your travel mode automatically.
Tap "Share Location" on the map. Passby uses your GPS position to search for real nearby places.
Color-coded pins drop for each category — green for parks, orange for landmarks, pink for restaurants, and more.
A Liquid Glass card slides up with a headline. Tap for the full detail view — Apple Intelligence streams a description in real time.
Passby automatically refreshes pins as you travel. Walk a quarter mile and new places load — no tapping required.
Every tool chosen deliberately. No third-party AI APIs — everything runs on-device or through Apple's own frameworks.
Fully declarative UI with Liquid Glass effects, native Tab API, and the latest SwiftUI APIs throughout.
On-device language model via LanguageModelSession. AI blurbs stream word-by-word with zero cloud cost and full privacy.
Real POIs via MKLocalPointsOfInterestRequest. Route trail via MapPolyline. No third-party map SDK needed.
Continuous GPS updates, speed detection, altitude tracking, and heading — all feeding the travel mode engine.
Real-time comments and persistent timeline synced to your account. Firestore security rules lock data to each user.
Privacy-first authentication. No passwords, no email required. One tap to create an account.
"Find places nearby in Passby" — registered via AppShortcutsProvider so Siri opens the app hands-free.
The entire app was designed, architected, and coded with Claude as the AI coding partner — from data models to SwiftUI animations.
